Carbohydrates are the body's primary source of energy, especially during extended workouts. They provide a quick-release form of energy, which is crucial for sustaining performance and endurance. During prolonged physical activities, stored carbohydrates, known as glycogen, are broken down to meet energy demands. Inadequate carbohydrate intake can result in fatigue, decreased performance, and longer recovery times. Including a balanced amount of complex carbohydrates in meals before and after workouts can enhance energy levels and support overall athletic performance.
